"Little devil, I see how long you can last!" The rickety old man wore a dark green mask, only showing a pair of gloomy eyes, staring at the workbench, his fingers on the crossbow, ready to shoot Du Di'an who was dying.

in vain

Whoosh!

A shadow suddenly flew out from behind the workbench.

The ricketed old man instinctively pressed his finger, and with a click, the crossbow arrow shot out, and the short arrow rushed out, but it did not hit the shadow, but was nailed to the wooden cabinet behind.

At this time, the shadow fell to the feet of the ricketed old man, and it was actually a realgar powder bottle.

His face changed, and he looked up hurriedly, only to see Du Dian jumping up from the ground, but instead of jumping around the workbench to pounce on him, he turned and jumped to the counter on the side, grabbing the bottles and jars above with both hands. I came across a few bottles and cans, fell to the ground and smashed them, scattering powder all over the place.

The rickety old man was burning with anger. This was all the experimental materials that he had collected and carefully ground. It was knocked to the ground like this. He gritted his teeth and quickly filled the crossbow arrow, aiming at Du Dian.

However, in the short time he refilled the crossbow, Du Dian had already retracted back under the workbench again.

"Damn little devil!!" The rickety old man was so angry that his eyes almost burst into flames, but several misses made him a little bit jealous of Du Dian, and he did not angrily go forward with a crossbow. Speaking of which, he didn't believe it himself, but he actually felt a threat from this child.

"I want to see how long you can last!" The rickety old man looked at the green mist that filled the secret room, and his eyes were as cold as frost.

"Caught!" Du Dian was holding a large glass bottle with half a bottle of sulfur powder in it. At this time, he felt that the oxygen in his lungs was getting less and less, and the suffocation was getting stronger and stronger. Looking around, looking for the fire sickle stone, however, although the things of the ricketed old man are scattered, there is no fire sickle nearby.

"No fire! No fire!"

Du Di was a little desperate in his heart. He finally thought of a way, but there was no fire. In vain, he saw the shadow above his head, which was reflected by the oil lamp. In an instant, he suddenly opened his eyes wide and looked at the place where the oil lamp was.

No deviation, no deviation, right at the table of the rickety old man.

The oil lamp, apparently for his work lighting, was not far from it.

The despair in Du Di's heart disappeared immediately, and at this time, he felt that his chest was about to explode, hurriedly took off his inner shirt, knotted the hem, and then poured the sulfur in the large glass bottle down the neckline Entering, immediately a full of sulphur powder in his inner shirt bulged, he gritted his teeth, life and death were at stake, and he threw the inner shirt out with a low growl in his heart.

Whoosh!

The ricketed old man watched a large group of black shadows fly over, instinctively pulled the trigger again, and the crossbow shot instantly, hitting the corner of his inner shirt. The sharp crossbow bolts penetrated in an instant and were nailed to the wooden cabinet at the rear. But the inner shirt that bulged like a ball fell to the rickety old man. His expression changed, worried about cheating, he hurriedly raised his hand to block it, and with a bang, the inner shirt was blocked by his arm and just fell on the table next to him. superior.

With a bang, the oil lamp was overturned, and the fire core burned with the overturned oil and water. The oil and water flowed onto the inner shirt and immediately burned.

When Du Di'an heard the crossbow bolts nailed to the wooden cabinet, he raised his head, knowing that the rickety old man hadn't filled the second crossbow bolt so quickly for a while, just when he saw the inner shirt burning, his face changed and he hurriedly fell down.

Bang! ! !

Suddenly, a thunderous explosion sounded, and several pieces of the wooden board on the top of the secret room collapsed, and a large amount of sand and dust poured down.

Du Di'an only felt that the worktable in front was knocked over by a huge force and hit him, and the corners were knocked against his ribs. Tears came out of the pain, and he almost fainted.

At this time, his breath-holding could no longer be maintained. Although he tried his best to restrain himself, he still inhaled a gust of air, which was full of fishy and sulphurous odors.

At this time, where the top of the head collapsed, the cold wind swept in and rolled out the sulphur and green mist in the air. Du Di'an was paralyzed on the ground, tightened his chest, and inhaled the air very slowly. The previous sulphur exploded, The green mist in the secret room was also washed away a lot. At this moment, it flew into the outside with the dust mist of sulfur. The smell was much lighter.

After a while, Du Di'an felt that he was barely able to move, and immediately climbed up slowly. The secret room had been blown up, and no one knew when it would completely collapse. He didn't want to be buried alive by the sand!

The previous explosion blew out all the oil lamps in the secret room. At this moment, the secret room was like a deep pit in the desert, and it was dark inside.

Du Dian gritted his teeth slightly, and with the faint starlight, groped towards the rickety old man, bumping his feet along the way, all collapsed wooden cabinets and tables. Relying on the distance and terrain he had previously remembered, he quickly touched the location of the rickety old man. The first thing he touched was the table that was turned over. He groped along the table, and immediately felt a mass of wet and sticky things, and then carefully touched it. Touched, and immediately his face became ugly.

There was a hard object inside that wet sticky thing, like a bone.

Although it was in the dark, he seemed to see the terrifying appearance of the rickety old man lying in front of him being blown to pieces. He felt chills everywhere. He didn't expect the power of this sulphur explosion to be so terrifying. Black powder, the reason why it heats up and explodes is entirely the principle of dust explosion.

"I killed" Du Di's heart trembled slightly, this is a human life, although he has seen too many broken and poor, and distorted laws in this world, but killing with his own hands is something he can't even think about. For a while, I only felt that in the darkness around, there seemed to be the ghost of the other party, staring coldly at him behind the invisible.

He shivered slightly, gritted his teeth, and secretly said in his heart: "I'm protecting myself, no wonder I, I'm just protecting myself, I didn't commit a crime." Thinking of this, he suddenly clenched his fists, his heart was full of sadness, the law he obeyed, He has long since disappeared from this world. Even if he commits a crime, who can convict him?

He smiled bitterly. In this dark pit, in this place where the stars can't shine, he suddenly felt so lonely, as if he had been forgotten by the whole world. This lonely loneliness gradually made his body tremble. He relaxed, and suddenly he was not so scared. Instead, there was a faint indifference. He silently looked at the dark place of the rickety old man's body. After a long time, he slowly moved his body, but instead of leaving, he bent down and Explore the ground.

He's looking for that crossbow!
